Abstract
A voltage regulator circuit includes a linear voltage regulator having a pass transistor and a first feedback from an output load, and a switching regulator having a second feedback from a voltage drop across the pass transistor. The voltage regulator further includes an efficiency monitor configured to detect the voltage drop and control predetermined steps of a duty cycle of the switching regulator based on the voltage drop.
